Iris are generally planted 12 to 24 inches apart. Close planting gives an immediate effect, but closely planted iris will need to be thinned often. Plants spaced further apart will need less frequent thinning. Many people plant them in small groups of say, three or five or seven; to give a massed effect. Newly set iris need moisture to help their root systems become established. Specific watering information depends on your climate and your soil, but remember that deep watering at long intervals is better than more frequent shallow waterings. Once established, iris normally don't need to be watered except in really dry areas. Overwatering is not desirable, but many people make this mistake. Specific fertilizer recommendations depend on your soil type, but generally an all-purpose food or a 6-10-10 are the way to go; just keep it low in nitrogen. A light application in the early spring and another application about a month after bloom is a good idea. Avoid using anything high in nitrogen, as nitrogen encourages rot. You can also give one more light feed after the growing season in order to encourage healthy growth for the next season. You will need to divide your iris before they become overcrowded, generally every 3-4 years. If too crowded the bloom will suffer, some varieties may crowd others out, and disease problems may be occur. Old clumps may be thinned by removing the old divisions at the centers of the clumps and leaving new growth in the ground. Or, you may dig up the entire clump and repalnt wiht the smaller, new, and healthier ones.

I think I'm in the same zone as you but I'm on the N.Olympic Peninsula, I believe you get more rain & heat than I do, lucky you! You should be able to grow some lovely Teas, we just don't get the heat in the summer. I read somewhere that roses with 35-40 petals do better for our climate, less balling of the blooms. You might want to try Peter Kukielski's book 'Roses without Chemicals, lots of good suggestions including regional picks. I grow one marvellous old (1910) white HT, Mme Jules Bouche that seems to fit your requirements, lovely fragrance, thick petals & stands up to the rain well.HMF says it gets BS but it's so minimal I just pluck off the leaves. Oh, I also was intrigued by Triple Delight. Let us know if you get it. Jane

Mina, for in front of the windows, I'd consider Osmanthus.....'Goshiki' or O. delavayi or x burkwoodii.....or Pieris 'White Cascade'. For something lower growing and with lots of sun, Hebe 'Caledonia' (has that purple coloration you favor) or Hebe anomola 'Purpurea Nana'. I might do clusters of heuchera for some of the edging plants - they do exceptionally well in our climate, are evergreen, and come in a wide range of colors to compliment any of the other plantings. One of my favorites is 'Green Spice', which has marbled green foliage with darker veining that turns an intense burgundy color in winter. Or any of the dark colored ones if you wish to add more purple foliage. Many of these are Great Plant Picks selections so should be available at any of our better retail nurseries.

Thank You for helping me by answer my question @gardengal48 i’m So worriEd to purchase that 2 flowers, because i dont Want to waste my money have a good day❤️
