Another Rose versus Drought-Resistant Shrub?
Comments (37)Perhaps Hulthemias might be good for "dry areas", but these are only "Hulthemias" due to the "blotch", the red petal base. Otherwise, they are pretty much garden roses, with all that infers. It's pretty obvious Eyes on You is a budded rose, and from the looks of the roots, it's pretty certain it's on Huey, so though it's a fun looking rose, it's not going to be a Cal. Native candidate. Diane, these are planted in what appears to be xerimulch with a sooty "soil" mixed in. The pulp pots are about a two gallon size with a plastic POP liner, like a traditional "body bag" packaging, only around the pulp pot. They're pretty heavy and too large for a large Priority box, unfortunately. Any plans on another visit back down to your friends in Valencia this year? Or, if you want to take your chances with a bare rooted, potted plant which is already developing roots and pushing growth buds....Kim...See MoreExperience with perennial geraniums in Upstate?
Comments (7)Geranium sanguineum does well here, and i've heard tuberosum does well, too, though i haven't grown it myself. They all seem to prefer part shade- i bet they'd melt in full sun. You're the same zone as us, so it should work. Ladies mantle i've killed more times than i like to contemplate. Some of the common spurges/euphorbias are a reasonable & easy to grow substitute for the green yellow flowers in spring (robb's especially). Coral bells do well in part shade for me. Spotted ligularia likes the spot i found with about 3 hours sun. They all like reasonably moist soil- i doubt they'd be happy on dry sand for long. I garden mostly in clay that's been amended. Good luck!...See MoreHardy Geraniums in Texas? "Vision Violet" or "Roseann"?
Comments (2)I was hoping someone closer to your climate would be able to answer this for you, since I have never gardened in Texas or any place similar. That said, I don't think any of the perennial geranium forms do well in prolonged heat. We had extended heat and drought last summer (week after week in the 90s and sometimes above 100) and all of my geraniums looked unhappy. True, they were newly planted that spring but, even with attention to supplemental water, many died, stopped growing and/or shriveled in size. Some of them came back and had a bit of a second wind when temperatures finally moderated in September and October. Of all of them, 'Rozanne' was the only geranium that tried to bloom during the heat. It didn't grow hardly at all but still kept producing a small quantity of blooms. Heat makes the blooms on this cultivar become tiny, washed out and pinky in tone. In cooler weather, they are much larger and fuller and can approach a true irridescent blue color. If you can provide some afternoon shade and regular water, this one might work for you. I find in general that any plant sold by Plant Delights Nursery in North Carolina will have good heat tolerance. They list 'Rozanne' along with several other geraniums....See MoreDrought tolerant Geraniums? .
Comments (7)If you look at where a great many geranium species grow natively - in areas surrounding the Mediterranean, in open meadows, rocky outcroppings or stony screes - it should be apparent that these are quite likely to be rather drought tolerant, subsisting on only natural rainfall in what tends to be dry, often arid areas. There are some exceptions of course but on the whole, most hardy geraniums are rather drought tolerant once established. They often don't mind supplemental irrigation but most do not require much of it. The Gardeners Guide to Growing Hardy Geraniums is an excellent monograph on this genus that discusses cultural needs in some detail. A few the authors note as being particularly well-adapted to hot, dry sunny locations are G. endressii, x riversleaianum, maderense, cinerium, sanguineum and tuberosum. And quite a few more species and hybrids will tolerate quite dry conditions if provided at least partial shade. These include macrorrhizum, nodosom, x oxonianum and x catabrigiense. Ivy leaf geraniums are pelargoniums and do require a bit different growing conditions. And as most in commerce are very highly hybridized, specific qualities like drought tolerance are a bit of a toss up. For best performance on these, I'd recommend routine irrigation....See Moredara_gardener-Vancouver Island, Z8
