my bowles mauve is now 4 years old and still going strong.. i dead head as soon as hte flowers have gone half way up the stem.. i cut back a bit each year down to the thrid bud up.. to stop getting woody. and then i use them as cuttings.. i have found between jan and june is best time for these..
i also have a stars and stripe variegated pink/red one.. an apricot one which i love.. it is mixed apricot pink and orange.. gorgeous.. these not so tough as bowles one thou.. so take cuttings each year..
i also grown my own wallflowers this year instead of buying them.. saved last years seed and i now have loads of plants.. so many i am selling them up top garden in 9cm for 25p each.. going well they are..
