flowered preservative , available from florists , contain sugars , acids and bacteriacides that can strain cut efflorescence aliveness . These come in low packets and are broadly speaking available where cut flowers are sold . If used properly , these can extend the vase lifetime of some cut blossom 2 to 3 times when compare with just plain water in the vase . Glossary : Ground CoverAground coveris any humbled growing plant that is planted in a mass to cover the flat coat .
