‘Firecracker’ is one of John Fisher’s deliberate hybrids of splendens x hirtella, an interesting cross!!! With that sort of parentage it survives winter better than could be expected though it would be risky below zero.
A smallish plant up to a metre and not real fussy about location. Bright red flowers with a dark calyx for a long time.
‘Petardo’ is a similar cross but the flowers are purple. Petardo meaning firecracker in Spanish!
