The Himalayan peony is a diploid nothospecies with ten chromosomes (2n=10), that results from hybridisation between P. lactiflora and P. mairei. [4] This large species of perennial herbaceous peony with hairless stems of 60–150 cm high, has large deep-cut leaves of 30–60 cm long, with up to fifteen hairless, lanceolate pointed leaflets or lobes of up to 14 cm.
Paeonia brownii is a glaucous, summer hibernating, perennial herbaceous plant of 25–40 cm high with up to ten stems per plant, which grow from a large, fleshy root. Each pinkish stem is somewhat decumbent and has five to eight twice compound or deeply incised, bluish green, hairless, somewhat fleshy leaves which may develop purple-tinged edges when temperatures are low.
Paeonia ludlowii is a deciduous shrub of medium height, belonging to the tree peony section Moutan of the genus Paeonia, and endemic to southeast Tibet. In Tibet it is known as ≠'lumaidao' meaning "God's flower". The vernacular name in Chinese is 大花黄牡丹 (da hua huang mu dan) meaning "big
Tree peony hybrid 'Maxime Cornu' of the P. × lemoinei group, is a hybrid between subsection Delavayana (P. delavayi) and subsection Vaginatae (P. suffruticosa 'La Ville de Saint-Denis'). Tree peony is the vernacular name for the section Moutan of the plant genus Paeonia , or one of the species or cultivars belonging to this section.
Paeonia × suffruticosa is the name used for most tree peony cultivars, but is not a naturally occurring species, so it can be regarded as the name for a man-made hybrid swarm. Genetic analysis has shown that five species of the subsection Vaginatae together make up the parentage of the tree peony cultivars created before World War II.
Production of new individuals along a leaf margin of the air plant, Kalanchoe pinnata. The small plant in front is about 1 cm tall. The concept of "individual" is stretched by this process. Kalanchoe daigremontiana produces plantlets along the margins of its leaves. When they are mature enough, they drop off and root in any suitable soil beneath.
Division is one of the three main methods used by gardeners to increase stocks of plants (the other two are seed-sowing and cuttings). Division is usually applied to mature perennial plants, but may also be used for shrubs with suckering roots, such as gaultheria, kerria and sarcococca.
Paeonia clusii is a relatively low (25–50 cm) species of herbaceous peony with scented, white or pink flowers of up to 12 cm in diameter. In the wild, the species can only be found on the islands of Crete and Karpathos (subsp. clusii), and Rhodes (subsp. rhodia). It has pinkish-purple stem up to 30 cm long and glaucous dissected leaves.
