google DAVE WILSON DOORYARD ORCHARD... his motto: the ultimate size of a fruit tree is up to the owner. but, if you're still interested, google "flying dragon citrus rootstock." also -- check out jene's tropical fruit in st pete -- they carry a miniature avocado and several condo mangoes. also -- willis orchard co has some varieties of mulberry and pomegranate that are smallish. just remember -- whatever they say the ultimate size will be is a lie. it's always bigger.

Welcome to the Deep South, Amy! I lived on Lake Ponchartrain's North Shore for a while, and so can tell you a few things that I noticed did really well. Lilium Formosanum, which blooms in August and September, is the best real lily for you to grow. Growing from seed, or buying only seed-grown bulbs is the best way to be sure you're getting virus-free plants. But Formosa Lily grows in the ditches on the Northshore, so this is not a fussy plant. The bloom stalks can reach eight feet. It looks like a giant Easter Lily. Crinums are an absolutely foolproof bulb, with beautiful strap-like leaves, and lily-like flowers. They love our Southern heat. A clump of Crinum can last for generations. Paper White Narcissus, which may be borderline tender in New York, will thrive down here, along with a number of selections from the Daffodil/Narcissus clan. Crocosmia seem to do well here. I imagine you've seen or grown them in New York, too. Lycoris is another bulb that loves our heat. I spotted a colony of Golden Lycoris (Aurea) on a lawn opposite 'Friends' restaurant in Madisonville, La. Since then, I've seen a few scattered about. Daturas/Brugmansia positively ADORE Louisiana. I remember seeing one plant in Terrytown, in full bloom near Christmas, reaching the soffit line of a little ranch house with its giant yellow blooms. Four-O'-Clocks love Louisiana, too, and are perennial there. Morning Glories are perennial in the New Orleans area. Daylilies do well everywhere, but you have the opportunity to grow the evergreen varieties not hardy farther north. Louisiana Iris are an obvious fit, with both wild types, and an endless array of fancy hybrids, to choose from. Even here in Madison, Mississippi, many Gladiolus (not just the 'hardy' ones) are hardy. They're popping up, right now, all over my neighborhood. I'd imagine 50% of the ones you'd buy in a bargain mixture would come back the next year (and start multiplying) in your climate. Landscapers use lots of Agapanthus down your way. My favorite is 'Elaine', with intense Gentian blue blooms. Also in an array of blues are Plumbago. This is a favorite in Uptown New Orleans, cascading out of pots, and used as a bedding plant. Here in Madison, Snapdragons are used as winter-blooming bedding plants. Likewise, you can count on Pansies and Violas for blooms from October until May. As for 'Tropical' plants, I'd try Monstera Deliciosa, which you can see in Terrytown, reaching the eaves of some rather squat little 60s-modern houses. In New York, you've seen it as a house plant. Our native Palmettos are great as eye-level palms. AND DON'T MISS THE GINGERS! Most of the ornamental Gingers are hardy in Ascension Parish. I'd start with the basic white 'Butterfly' Ginger (most wonderful fragrance possible), and expand my collection from there. Gingers form big colonies, and are pretty foolproof. Canna lilies, I'm sure you've seen in New York. Here, they are absolutely hardy, and grow like crazy. There are native varieties growing in the ditches of St. Tammany Parish, plus countless 'improved' cultivars. 'Bengal' and 'Praetoria' are two 'fancy store-bought' cultivars in vogue right now, but most anybody you meet will probably share a clump of whatever kind they have growing. I bought Cannas mislabeled as 'City of Portland' (Lowe's) and got a wild variety with vermillion blooms that seem to pull the Humming Birds down out of the sky. Had zero hummers before those Cannas arrived. Now, they drop in all summer long. You didn't ask about shrubs, but I will mention the top three must-have categories; Citrus, Camellias, and Roses. I'd go for miniature citrus trees. I grew Meyer Lemon, in pots, on the Northshore. They'd come inside (still sporting lemons) around Christmas. They'd bloom inside (incredible fragrance), and I'd hand-pollinate. But plenty of people grow Oranges, Kumquats, and Meyer lemons outside. Miniature citrus can be covered during rare cold snaps. I think finding the right sun-trap against the house is the tricky part. The grandfather of one of my friends brought lemon seeds to Jackson Mississippi from Palermo. His tree became large enough, over fifty years, to have a sizable trunk. Your climate is far warmer than Jackson's. Camellia Sassanqua starts blooming around October, and blooms into December, which is when Camellia Japonica begins to bloom. I have Camellia Vernalis, which blooms November-December. Sassanqua likes more sun, and puts on the greatest show. The more compact double pink varieties absolutely explode with bloom, when they are happy. They are usually happy. As for roses, an aunt in South Carolina passed along a little mnemonic device that applies all over the Deep South: "Polyantha Noisette likes her Tea in a China Cup." But in your neck of the woods, I'd skip the Polyanthas and Noisettes, and stick to roses that are as close as possible to the old garden varieties of Southern China. Ashdown Roses, Antique Rose Emporium, and many others, offer antique roses ideal for your area. I'd start with 'Mrs. Dudley Cross', which, once established, will require no care at all. This is a Tea (as opposed to hybrid tea), with soft pink/creme blooms. Just be sure it was grown on its own roots. Most grafted rootstocks are inappropriate for the Deep South. Hope this is good for a start, and, once again, welcome to our part of the world!

my guava fruit all summer and fall. in spring they are rebuilding leaves and flowers. mexican cream is softer and aromatic. i love the aroma and flavor. i have a pink which is really good also (its a bit harder) , didnt like the white too much. call Pine Island. they should have a few good ones. you can look into Jaboticaba and Grumichama also should fruit compact, although Jabo grows a bit slower. my 3gal still started fruiting 1 yr after i got it (just 8 fruit) but i should get more this year. http://www.tropicalfruitnursery.com/fruitproducts_gl.htm

Wait until your Spring, when both your tree and the rootstock are actively growing. Ask your local nurseryman for a good rootstock for your area; get 10; then do 10 T-buds or chip buds; and if you do them carefully, you should get at least 2 or 3 to take. When they are strong and growing well, I would take out the old tree or leave it and put the new tree(s) in another place. You can prune the old tree quite heavily, if you want to save it; as long as the trunk is solid and healthy; it will grow new shoots. BTW, one of the reasons the oranges from the old tree taste so good is the age of the tree; the new grafted trees should produce fruit in a year or two and they will be "clones" of the existing tree. Be warned, though... fruits from the new trees may not taste as good for a few years.
