A most exotic looking large perennial pea from Mexico, with strong growth to about 2.5m. Pinnate foliage has leaflets with indented tips, giving a very distinct effect. Highly conspicuous large pale green, but heavily purple-red stained, stipules on the stems and large deep yellow pea flowers in late summer and autumn, makes for a striking specimen! Absolutely bone hardy in my experience, even through Dec' 2010 here at -14c, without a mulch, though young specimens are less tough and gain hardiness with establishment. Sun.
