Mr. Bluebird  A charming little rose with semi-double flowers of a lovely bluish-lavender colouring.  The growth is compact and bushy.  In every way an excellent variety of considerable garden value.  The breeding is recorded as ‘Old Blush China’ x ‘Old Blush China’.  I understand that self-set seed was sown and this resulted in a high proportion of Miniature seedlings.  These must surely have been chance hybrids with a Miniature Rose.  Moore (U.S.A.), 1960.

Then, more recently I have grown three different lots in different years of self-set seed gathered from an isolated plant of ‘Old Blush’ (Parson’s Pink China) – supposedly in cultivation before 1759.  Germination was rather poor, but from the first lot a number of the seedlings were definitely of the miniature type.  In seven years several of these have grown no more than seven to twelve inches in height.  One (only seven inches high) is  semi-double with flowers the same colour as Rosa roulettii.  Another grew only about eight inches high with tiny double flowers resembling the miniature ‘Peggy Grant’.  Another grew about ten inches with double flowers resembling ‘Pink Joy’ (a seedling of Oakington Ruby’) in both colour and form.  Yet another produced one and a quarter inch semi-double lavender blue (magenta) flowers on a twelve inch plant.    Several set seed heps but seeds often contained no embryo.  Germination has been very poor from any of these seedlings.  However, some seedlings of the lavender blue (Mr. Bluebird) cultivar have been grown.  All are miniature – usually with very narrow lance-shaped petals and so far all have been female sterile but some pollen is produced. The other lots grown from ’Old Blush’, although in smaller lots, gave similar results.

Mister Bluebird, Min. (R. Moore, 1960) 'Old Blush' x 'Old Blush'. Semi-double lavender-blue florets in clusters. Bushy and grows to about fifteen inches. The flowers do not seem to last well after cutting - this may improve on older plants. I prefer 'Baby Faurax'.
