Plant ID Plant name Culture ht X width(in) Zone Description
197 Tanacetum densum amanum 6X24 5 A drought tolerant ground cover for sunny areas. Intensely silver-white leaves are very finely cut, hence the common name, “Partridge Feather Tansy”. Spikes of yellow buttons in late spring to summer. Plant near something blue for a beautiful combo. We suggest Penstemon heterophyllus. We have heard that it succeeds in shade as well, but have not tried it. DR
963 Tanacetum heterotomum 6X15 5 We know nothing about this except that it has silvery green leaves and small white flowers. Said to be slow growing. We have not yet trialed it in the open garden, obviously, or I could tell you something more about it.
195 Teucrium polium aureum 6X18 6 Mounds of silver woolly foliage, very pettable. The flowers are yellow, enhanced by chartreuse bracts. Wonderful at the foot of a lavender or tumbling over a rock wall in the deer resistant garden. DR
201 Teucrium pyrenaicum 3X15 5 Native of the Pyrenees with nice mats of dark green leaves that are arranged in symmetrical whorls on short stems. Small flowers are cream and maroon and something between cute and elegant. DR TNT
901 Thymus cappadocicus globifer 4X12 A dense woody thyme from Turkey with short linear leaves and flower heads ranging from clear white to pale lilac. We have not trialed it yet. DR
341 Thymus comosus 3X12 5 Nice low mats of dark green leaves and showy heads of pink flowers. Blooms late in the summer when there is not much color. Like all thymes, it is great for butterflies. DR TNT
207 Thymus leucotrichus 8X20 Nice shrubby thyme with silvery leaves that almost give it the appearance of a dwarf conifer. Lavender flowers completely cover the mound for a long time in spring. DR TNT
347 Thymus mastichina 8X18 6 Loose mounds of green leaves are topped with heads of white flowers very late in the summer. Adds a nice touch to the late summer and early autumn garden. DR TNT
664 Thymus striatus A Croatian thyme with dwarf prostrate woody stems and purple-pink flowers. DR
338 Townsendia hookeri 2X4 4 Dense tufted cusions of narrow linear grey leaves. Large bright white daisies nestle into the cushion. Short lived in the garden, like almost all Townsendias, but reseeds. WN DR
209 Townsendia parryi 5X3 First year forms neat rosette of perfectly symmetrical blue-green leaves. The next year it produces relatively huge lavender daisies on short stems 1-5 inches tall. Usually monocarpic (dies after flowering), but sets copious amounts of seeds. Wonderful around Eriogonum. CA WN DR TNT
247 Townsendia scapigera 2X3 A tiny Easter Daisy forming mounds of grey topped with relatively large pale lavender daisies. Native to volcanic slopes in from California to Idaho. Short lived, but reseeds well and is tiny enough for a trough. CA WN DR TNT
335 Townsendia spathulata 2X5 A very special Townsendia. Rosettes of silver hairy spatulate leaves form small domed cushions. Stemless bright purple flowers. For troughs. WN DR
