There are two "N" flowers that I like one of which I've not grown for many years, nor have I seen it grown in other gardens, it is:
"NEMESIA is a genus of annuals, perennials and sub-shrubs which are native to sandy coasts or disturbed ground in South Africa. Numerous hybrids have been selected, and the annual cultivars are popular with gardeners as bedding plants.
The flowers are two-lipped with the upper lip consisting of four obes and the lower two lobes."
The second "N" is growing in our garden right now although at the end of its season. It is:
"NASTURTIUM is a genus of seven plant species in the family Brassicaceae (cabbage family). These plants are related to watercress and mustard, noteworthy for a peppery, tangy (pungent) flavour.
The name nasturtium comes from the Latin nasus tortus, meaning "twisted nose", in reference to the effect on the nasal passages of eating the plant."
Many years ago, in a small garden bed near our front door, I sowed some nasturtium seed that were many years out of date. We got a full crop of them and they were beautiful. Now they self-seed every year and we have nasturtiums everywhere, more especially in our back garden. There are so many beautiful colours and to see them is to love them.
I do remember using the leaves in sandwiches (probably instead of lettuce) way back but haven't done so probably for 40 years or more. I wonder if I dare try them now especially having read the statement re effects on the nose, I have enough allergies now so perhaps not.
