The early milestone birthdays are the 18th, 21st, 30th and 40th, and each one comes with a different mood. At 18 and 21 the emphasis is on colour and fun. At 30 and 40 it shifts towards something a little more grown-up.

MyFlowers files the bouquets here under its 18th, 21st, 30th and 40th birthday collections. For the younger birthdays, choose brighter colours: hot pink roses, red and lilac, a fresh pastel. For the older ones, soft peach, cream and blue hydrangea suit a more settled taste.

As with any birthday bouquet, a card with a personal line matters more than the number of stems. Delivery is available across the UK, and MyFlowers states that same-day delivery is possible on orders placed in time. Prices shown are for the smallest size.

Questions people ask

What flowers are best for a 21st birthday?

Bright, cheerful colours suit a 21st: hot pink roses, red and lilac, or a fresh pastel mix. Pair with a card and a small gift.

What flowers are good for a 30th birthday?

A soft, slightly more grown-up bunch works well, such as peach roses, pink carnations or sunflowers. It is a good moment for something that looks considered.

What flowers suit a 40th birthday?

Blue hydrangea, peach roses and soft pink bouquets all feel celebratory without looking childish. Add a card that is personal.
