Macfadiena, etc. is a native here in Argentina. It is a very large bignonia that produces a stunning explosion of yellow flowers that is over in a few days. No one grows it as it is a weed with no garden value 8except the fugacious bloom).
Akebia loves good soils and once established is very drought resistant. Foliage is perennial and very attractive and the flowers are striking (there is a spectacular bicolor form). It grows well in shade even deep sahde and makes a fin ground cover. BUt, over the years the tidy nice plant of the first years becomes a rampant huge thing that layers and smothers everything at hand.
